WASHINGTON I. TUTTLE, OF BALTIMORE, MARYLAND, ASSIGNOR TO THE AMERCANTOBACCO COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

OLLAPSIB BOX.

No. esente.

To all whom it may concern.' i

Be it known that i, WASHINGTON lL` TUT'rLn, a citizen of the UnitedStates, residing at Baltimore, in the State of Maryland, have inventednew and useful lm rovements in Collapsible Boxes, of Whic the followingis a specification.

The present invention relates to collapsible boxes of that type in whichpacked goods or commodities are sold, and which, after the originalcontents have been consu-med, may be readily utilized for otherpurposes, particularly as lunch hits or pails.

The present invention is intended articularly as an original package inW lich tobacco may be packed and sold, it being so designed as that itwill form a compact, secure receptacle for tobacco when it is inYcollapsed condition, and one which may be readi y packed and shippedand handled by. the retailer, but which, after the purchaser hasconsumed the contents, is convertible into a convenient extensible lunchbucket.

Broadly considered, this type of box is not new, and my presentimprovements have to do with certain structural details whereby a morecompact and rigidarrangement. of collapsible sections is secured, and abox is provided which is better calculated to meet the needs of theoriginal use ior which it is designed, namely, a tobaccol package, asWell as the needs of a lunch kit, to which use it is put after itscontents have been used.

Briefly stated the invention com )rises a plurality of telescopingsections wiich, in the present instance, are shown as interiorlytelescoping sections, which, in collapsed condition, provide a box orrece tacle having a substantially unbroken interior surface, and which,in extended position, gives receptacleof considerable capacity. The boxis provided with'a hollow top whichis designed to be reversed so thatwhen the box is in collapsed position, the cover has an ordinary smoothtOPmWhile in the reversed condition of the cover it has a filling funneland closing ca through which the hollow to may be fil ed with coffee orother liquid diiring the use of the box as a lunch kit.

In order that the invention may be understood by those skilled in theart, to Whom Vthis disclosure is addressed, l have shown in theaccon'lpanying drawings one embodie ment oi' my invention, and in suchdraw- 1ngs:-s-

Fig. 4 is a transverse sectional view of thei box colla sed. Fig. 5 is adetail view of a portion ot the end of the box to show the provisioni'or the lap seams of the box. Fig. 6 is a detail view of the stop andbail ear with which the box is provided. Fig. 7 is a detail sectionalview to show the relation of the lap seams ofthe box sections to oneanother. Fig. S'is a transverse section of the meeting ribs between twooi the sections taken on the line of the lap seam. Fig. 9 is :s

a detail View of a slightly modiiied form of cover.

Referring to the drawings by numerals, like numbers indicating likeparts in the several views, 2 indicates the outer section of the box,which, as shown, is open at vtop and botrovided at its bott-oni with aniii-turned rilla 3 and at its top 'with an outturned rib 4, asis clear]y shown in Fig. 2, these ribs serving to stillen the section, and in thecase oi the lower rib 3 forming the means which engages the adjacenttelescopingseetion, and these ribs may, ii desired, be stiliened byiwire centers in the usual manner. Within the saidouter section, andtelescoping in contact with the inner wall thereof, is the next section5 which is onen at the top and bottom and is j(n'ovideL with theoutturned top rib 6 and the iii-turned bottom rib 7, as shown, theout-turned rib on this section 5 engaging the in-turncd rib 3 at thebottoni of the section, as shown in Fig. 3.

The inner section S is shown in the present instance as beingthe'bottonl section of the series of three sections shown in the presentcase, although it is obvious that any number oi sections, may beemployed, and this said inner section 8 has at its top the out-turnedrib 9, designed to engage the iii-turned rib 7 on the intermediatesection when the box is This inner section 8 has securcdto its loweredge the bottoni it), which is secured thereto, by a suitable crimp 11engaging the lower edge oll the section 3 in the manner shown in Fig. 2.

. meeting ends by means ol the ordinary seam 12, as shown in Fig. 7, andyet not 1nln order that the sheet metal of which these sections areformed may be cheaply and conveniently secured together at their lap Ithereby reducing the chances of displace-- ment and j amming of thesections. y Y

In order that the several sections may not 'be displaced by beingtelescoped upwardly out of their nested relation with eac 1 other,lcprornde a stop 14 against which. the upper e ges or the sectionsstrike when the box is in collapsed position'and by means of which sslip cover 22 is exten they are revented from being disengaged, it beingo vious that the engagni ribs or the several sections will prevent t csections being disengaged in their downward vmovements and extended tothe extended position shown in Fio'. 3, and by this arrangement ot ribs,which prevent the sections being disengaged when extended, and the stops141 which prevent the sections being disengaged when colla sed, asectional box is provided in. which al danger of arts becomingdisarranged or disconnects and perha s lost, .is avoided. 'lhese stops14 are preierably 1n the form shownand comprise the forkedsingularly-placed member and the vertical attaching member, the forkingof `the niember 14 being desirable in order that the vertical attachingmember may be readily bulged at 15 to engage or rovide for the bulge o1the lap seam 12. he said sto 14 is preferably and conveniently secure( bpassing the securin tongue 16 of the bail carrving ears direct y throughthe material i of the box and. the stop member 14 and clenching themdown in the manner shown in Figs` 1, 5 and nShe cover 17 is made asshown in the forni oi a 'shallow receptacle, being preferably made up intwo parts joined by a lap seam which is extended to provide a cover orlid rim 1S which rests on the top of the outer section 2 When'the coveris in position.

The contour of the cover atits periphery is the saine on both sides,being curved as shown, in order that it may not only be easily enteredand held by frictional engagement With the box section 2, but When thebox is in collapsed position the said cover 17 will rest upon theinteriorly collapsed sections of ity to the otherwise flexible sheet, W

:the parts to ese-eas the box, as clearly shown in Fig. 4, and willeiectually tions so that an absolutely tight closure is provided for allof the sections of the box, and. this l consider to be ci' asit preventsboth the escape of the contents of the the to s of the niner sectionsand Working down etween the Walls of the sections, but it-also preventsthe-ingress of dust or dirt which mi ht Work in between the sections andover t eir topsinto the package.

Preferably, top 17, l stamp or rib the same at t a e point 19, thisstamping or the metal givin a rigidich aids materially 1n resistingbuckling strains. The other side of the to 17 is providedwith the funnelor neck 20 wiich receives ythe slip cover 21, and it will be observedthat in coilapsed condition as shovvn in Figs. 2 and d,

1n the form of the tol ed so that when in"a serted its lower edge bearsagainst'and braces the opposite side ci the top 23 as shown, and: thisconstruction adds rigidity to the'top, enabling the same to be made oirelatively thin stock and yet avoid the danger of battering or bucklingthe top out ot shape during usage. A

p From the foregoing it will be seen that the construction of ox which lhave invented and herein disclosed, is such that a relativelyinexpensive stock may be used in making it up, no expensive seams orunions between permit the telescoping arrangement are necessary, and yeta box is provided which Will stand the ordinary handling to which. it issublected, both in the original packing and shlpping, and in using it asa Unch it after its original contents have been consumed,without dangerof becoming brokenror distorted so as to render it unfit for use.

It is obvious that the details of construction may be varied Without andyet be within the purview oi my invention, and l do not,4 therefore,limit myself to the details dise closed except in so lar as l am limitedby the prior art to which the invention belongs.
